[0038] like Figures 2 to 5 As shown, an embodiment of the present application provides a cigarette pack rejecting push plate 1 of a packaging machine and a packaging machine.
[0039] like Figure 1 As shown, the cigarette pack rejecting push plate 1 of the packaging machine includes a push plate body 11 and a mounting frame 12.
[0040] The push plate body 11 has a push surface 1A located on the side of the push plate body 11, and the push surface 1A is configured to fit with the unqualified cigarette packs 9A to push the unqualified cigarette packs 9A and remove the unqualified cigarette packs 9A from between the upper conveying plate 5 and the lower conveying plate 6 of the beam channel of the packaging machine.
[0041] The mounting frame 12 is located on the side of the push plate body 11 away from the pushing surface 1A, and includes a mounting portion for mounting the cigarette pack rejection push plate 1 on the rejection push rod 2 of the packaging machine. The push plate body 11 is connected to the mounting frame 12 and together with the mounting frame 12 forms a positioning surface 1B perpendicular to the pushing surface 1A. The positioning surface 1B is arranged at one end of the pushing surface 1A and is configured to be adjacent to the previous cigarette pack 9B adjacent to the unqualified cigarette pack 9A to determine the matching position of the pushing surface 1A and the unqualified cigarettes.
[0042] The push plate body 11 also has a first guide surface 1C, which is arranged on the same side of the push plate body 11 as the positioning surface 1B and connected to the positioning surface 1B. The first guide surface 1C gradually approaches the positioning surface 1B from away from the push surface 1A to close to the push surface 1A.
[0043] In the cigarette pack rejecting push plate 1 of the embodiment of the present application, since the push plate body 11 has a first guide surface 1C which is arranged on the same side as the positioning surface 1B and connected to the positioning surface 1B, and the first guide surface 1C gradually approaches the positioning surface 1B from a direction away from the push surface 1A to a direction close to the push surface 1A, when the cigarette pack rejecting push plate 1 returns after rejecting the unqualified cigarette pack 9A, the edge of the first guide surface 1C away from the push surface 1B enters the conveying plate 5 and the beam frame on the beam frame channel before the edge close to the push surface 1B Between the conveying plates 6 under the channel, and the edge away from the pushing surface 1B is relatively far away from the positioning surface 1B compared with the previous cigarette pack 9B. As the cigarette pack rejection push plate 1 continues to retreat, under the guidance of the first guide surface 1C, the part of the positioning surface 1B located on the push plate body 11 smoothly enters between the conveying plate 5 on the beam channel and the conveying plate 6 under the beam channel, thereby preventing the previous cigarette pack 9B from being scratched by the edge of the push plate body 11, thereby protecting the previous cigarette pack 9B and reducing the hidden danger of damage to the previous cigarette pack 9B.
[0044] In some embodiments of the cigarette packet rejection push plate 1, the first guide surface 1C is a plane, a curved surface, or a combination of a plane and a curved surface. Figures 2 to 5 In the illustrated embodiment, the first guide surface 1C is a plane.
[0045] In some embodiments of the cigarette packet rejection push plate 1, the cigarette packet rejection push plate 1 also includes a second guide surface 1D, which is located between the pushing surface 1A and the positioning surface 1B and gradually approaches the positioning surface 1B from the pushing surface 1A to the direction away from the pushing surface 1A.
[0046] During the process of the cigarette pack rejection push plate 1 rejecting unqualified cigarette packs 9A, when entering between the upper conveying plate 5 and the lower conveying plate 6 of the beam channel, the second guide surface 1D helps prevent the previous cigarette pack 9B from being scratched by the edge of the push plate body 11, thereby protecting the previous cigarette pack 9B and reducing the risk of damage to the previous cigarette pack 9B.
[0047] like Figures 2 to 5 As shown, in some embodiments of the cigarette packet rejection push plate 1, the second guide surface 1D is a plane, a curved surface, or a combination of a plane and a curved surface. Figures 2 to 5 In the illustrated embodiment, the second guide surface 1D is a plane.
[0048] like Figures 2 to 5 As shown, in some embodiments of the cigarette packet rejection push plate 1, the push plate body 11 further has an end surface 1E arranged at the end of the push plate body 11, and a chamfer 1F is formed between the end surface 1E and the pushing surface 1A, the positioning surface 1B and the first guide surface 1C. Figures 2 to 5 In the embodiment shown, the chamfer 1F continues between the end face 1E and the second guide face 1D.
[0049] The chamfer 1F is further helpful to prevent the previous cigarette pack 9B from being scratched by the edge of the push plate body 11, thereby protecting the previous cigarette pack 9B and reducing the hidden danger of damage to the previous cigarette pack 9B.
[0050] like Figures 2 to 5 As shown, in some embodiments of the cigarette packet rejection push plate 1, the push plate body 11 includes a push plate portion 111 and a guide plate portion 112. The push surface 1A is arranged on the side of the push plate portion 111. The guide plate portion 112 is arranged on a side of the push plate portion 111 away from the push surface 1A and close to the positioning surface 1B, forming an L-shaped plate with the push plate portion 111, and the first guide surface 1C is arranged on the guide plate portion 112.
[0051] The push plate body 11 includes a push plate portion 111 and a guide plate portion 112, which is beneficial for the first guide surface 1C to extend a longer distance along the moving direction of the push plate portion 111, so that the angle change of the first guide surface 1C relative to the positioning surface 1B is smaller, thereby facilitating the smooth relative movement between the cigarette pack rejection push plate 1 and the previous cigarette pack 9B, and further helps to prevent the previous cigarette pack 9B from being scratched by the edge of the push plate body 11, thereby protecting the previous cigarette pack 9B and reducing the hidden danger of damage to the previous cigarette pack 9B.
[0052] like Figures 2 to 5 As shown, in some embodiments of the cigarette pack rejection push plate 1, the positioning surface 1B is arranged on the push plate portion 111, the guide plate portion 112 and the mounting frame 12. This arrangement is conducive to increasing the portion of the positioning surface 1B located on the cigarette pack rejection push plate 1 to extend a longer distance along the moving direction of the push plate portion 111, which is conducive to the smooth relative movement between the cigarette pack rejection push plate 1 and the previous cigarette pack 9B, and further helps to prevent the previous cigarette pack 9B from being scratched by the edge of the push plate body 11, thereby protecting the previous cigarette pack 9B and reducing the hidden danger of damage to the previous cigarette pack 9B.
[0053] like Figures 2 to 5 As shown, in some embodiments of the cigarette packet rejection push plate 1, the guide plate portion 112 includes two guide plates respectively located on both sides of the mounting frame 12. This arrangement facilitates the smooth relative movement between the cigarette packet rejection push plate 1 and the previous cigarette packet 9B.
[0054] like Figures 2 to 5 As shown, in some embodiments of the cigarette pack rejection push plate 1, the mounting frame 12 includes a third guide surface 1G, the third guide surface 1G is located on the side of the first guide surface 1C away from the pushing surface 1A and is connected to the positioning surface 1B, and the third guide surface 1G gradually approaches the positioning surface 1B from the direction away from the pushing surface 1A to the direction close to the pushing surface 1A.
[0055] When the cigarette pack rejection push plate 1 rejects the unqualified cigarette pack 9A and then retreats, the edge of the third guide surface 1G away from the pushing surface 1B enters between the upper conveying plate 5 and the lower conveying plate 6 of the beam channel before the edge close to the pushing surface 1B, and the edge away from the pushing surface 1B is relatively farther away from the previous cigarette pack 9B than the positioning surface 1B. As the cigarette pack rejection push plate 1 continues to retreat, under the guidance of the third guide surface 1G, the part of the positioning surface 1B located on the mounting frame 12 smoothly enters between the upper conveying plate 5 and the lower conveying plate 6 of the beam channel, thereby preventing the previous cigarette pack 9B from being scratched by the edge of the mounting frame 12, thereby protecting the previous cigarette pack 9B and reducing the risk of damage to the previous cigarette pack 9B.
[0056] like Figures 3 to 5As shown, the embodiment of the present application also provides a packaging machine, including an upper conveying plate 5 of a beam channel, a lower conveying plate 6 of a beam channel, a cigarette pack rejecting push plate 1 and a rejecting push rod 2. The lower conveying plate 6 of the beam channel is arranged in parallel and spaced apart from the upper conveying plate 5 of the beam channel. The space between the upper conveying plate 5 of the beam channel and the lower conveying plate 6 of the beam channel is configured to place cigarette packs 9. The cigarette pack rejecting push plate 1 is the cigarette pack rejecting push plate 1 of the embodiment of the present application. The cigarette pack rejecting push plate 1 is mounted on the rejecting push rod 2 through the mounting portion of its mounting frame 12. The rejecting push rod 2 is configured to drive the pushing surface 1A of the cigarette pack rejecting push plate 1 to push unqualified cigarette packs 9A and reject the unqualified cigarette packs 9A from between the upper conveying plate 5 of the beam channel and the lower conveying plate 6 of the beam channel.
[0057] The packaging machine of the embodiment of the present application has the same advantages as the cigarette pack rejecting push plate 1 of the embodiment of the present application.
[0058] The following combination Figures 2 to 5 The packaging machine and the cigarette pack rejecting push plate 1 of the embodiment of the present application are further described.
[0059] like Figures 3 to 5 As shown, the packaging machine comprises an upper conveying plate 5 for the beam channel, a lower conveying plate 6 for the beam channel, a cigarette pack rejecting push plate 1 and a rejecting push rod 2. The lower conveying plate 6 for the beam channel is arranged in parallel and spaced below the upper conveying plate 5 for the beam channel. A plurality of cigarette packs 9 are placed side by side in the space between the upper conveying plate 5 for the beam channel and the lower conveying plate 6 for the beam channel.
[0060] The cigarette packet rejecting push plate 1 comprises a push plate body 11 and a mounting frame 12. The push plate body 11 comprises a push plate portion 111 and a guide plate portion 112, which form an L-shaped plate.
[0061] The mounting frame 12 includes mounting feet that are spaced side by side in an upper and lower manner, and the front sides of the two mounting feet are connected by a connecting plate. The mounting frame 12 includes a mounting portion for connecting the cigarette pack rejection push plate 1 and the rejection push rod 2. The mounting portion includes a first mounting hole 12A and a second mounting hole 12B. The front end of the rejection push rod 2 is located in the interval between the two mounting feet. The bolt 3 passes through the first mounting hole 12A and a corresponding through hole provided on the side of the front end of the rejection push rod 2, and cooperates with the nut 6. The screw 4 passes through the second mounting hole 12B and is threadedly engaged with the corresponding screw hole provided on the front end face of the rejection push rod 2. Thereby, the cigarette pack rejection push plate 1 is installed on the rejection push rod 2 through the mounting portion.
[0062] The rejection push rod 2 can move forward and backward under the drive of the driving device, thereby driving the cigarette pack rejection push plate 1 to move forward and backward to perform the rejection operation and the return operation of the unqualified cigarette pack 9A. The driving device is, for example, a motor or a driving cylinder.
[0063] The front end surface of the push plate portion 111 forms a push surface 1A. The first guide surface 1C is located on the left side of the guide plate portion 112. The positioning surface 1B is formed on the left side of the push plate portion 111, the guide plate portion 112, and the mounting frame 12. The first guide surface 1C is located behind the portion of the positioning surface 1B on the guide plate portion 112, and is a plane that gradually approaches the positioning surface 1B from right to left along the direction from back to front and is connected to the positioning surface 1B.
[0064] The second guide surface 1D is disposed at the left front corner of the push plate 111 and is a plane connecting the push surface 1A and the positioning surface 1B on the push plate 111. The second guide surface 1D gradually approaches the positioning surface 1B from front to back along the direction from right to left.
[0065] Chamfers 1F are provided between the end surface 1E of the pedal body 11 and a portion of the first guide surface 1C provided on the positioning surface 1B of the pedal body 11 , the second guide surface 1D, and the pushing surface 1A.
[0066] The third guide surface 1C is arranged on the left side of the rear part of the two mounting feet of the mounting frame 12, and is a plane which gradually approaches the positioning surface 1B and connects with the positioning surface 1B from right to left along the direction from back to front.
[0067] When performing the operation of removing unqualified cigarette packs 9A, as shown in FIG. Figure 3 As shown, the push surface 1A of the cigarette pack rejection push plate 1 is in contact with the rear surface of the unqualified cigarette pack 9A, and the cigarette pack rejection push plate 1 is driven by the rejection push rod 2 to move forward, and the unqualified cigarette pack 9A is pushed out from between the upper conveying plate 5 of the beam channel and the lower conveying plate 6 of the beam channel. When the rejection push rod 2 and the cigarette pack rejection push plate 1 push the unqualified cigarette pack 9A to a certain stroke, as shown in FIG. Figure 4 As shown, since the upper conveying plate 5 of the beam channel and the lower conveying plate 6 of the beam channel have a squeezing effect on the cigarette pack 9, the two sides of the cigarette pack 9 will expand and arch, causing the previous cigarette pack 9B to fit with the positioning surface 1B of the cigarette pack rejection push plate 1. When the unqualified cigarette pack 9A is rejected, the rejection push rod 2 drives the cigarette pack rejection push plate 1 to retreat during the return journey. Due to the guiding effect of the first guide surface 1C, it is helpful to prevent the previous cigarette pack 9B from being scratched by the edge of the push plate body 11, thereby protecting the previous cigarette pack 9B and reducing the risk of damage to the previous cigarette pack 9B.
[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and not to limit it. Although the present application has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present application can still be modified or some technical features can be replaced by equivalents, which should all be included in the scope of the technical solution requested for protection in this application.
